TO ALL WHOM IT MAY concerts;

Be it known that we, E. A. Scenes and E. L. MILLER, both ofPhiladelphia, Pennsylvania, have invented an Improvement in SewingMachines; and we do hereby declare the following to be a full, clear,and exact description of the-same, reference being had to theaccompanying drawing,'a nd to the letters of reference marked" thereon.I

Our invention ccnsists in the arrangement and combination, describedhereafter, of an inclined vibrating needle-arm, eye-pointed needle, anda vibrating loop-holder or carrier for making a button-hole stitch overthe edges of fabrics. On reference to the accompanying drawing, whichforms a part of this specification Figure 1 is aside view of suflicientof a sewing machine to illustrate our improvement.

Figure 2, the same, with the parts in difi'erent positions.

Figure 3, a front view and 7 Figures 5, and 6 illustrate the differentmodes of operating the loop-holder.

Similar letters refer to similar parts throughout the-several views.

A is the base of the machine, upon whiieh.is erected the standard B, andto the top of the latter is secured the work-plate G. E is thevneedle-arm,to the outer end of which is secured the ordinaryeye-pointed needle n, the said needle-arm being placed at such an anglethat it will carry the needle 11. in a diagonal path, coinciding withthe line X X, fig. 3. Through the standard 13 passes a rod, a, upon theouter end of whieh'is a toothed pinion, e, gearing into teeth on theedge of a segment,.F, thellatter being hung to a pin, e, on the side ofthe standard B. To the lower end of the segment F is connecteda rod, D,which is actuated from any moving part of the'machine by suitablemechanism. To the inner end of the rod (1 is secured a curvedloop-holdenb, ithrough eyes in which passes the under thread 3/, the upper thread xpassing through the eye of the needle a.

who diiferent parts of the machine being in the position shown in fig.1, (and in dotted lines, fig. 3,) and the cloth having been so placedupon the work-plate that the loop-holder b shall pass through thebutton-hole and in-fr0nt of the edge to be sewed, the machine is set inmotion. The needle 11. descends, perforating the fabric near the edge tobe sewed, until it reaches the limit of its downward movement, theloop-holder at the same time moving in the arc of a circlc through thebutton-hole from the position shown in fig. 1 to .that shown in fig. 2.As the needle it rises the loop-holder moves upwards, carrying the underthread through the loop of needle-thread, both holder and needle finallyreaching the limit of their upward movement, as seen in fig. 1. As theneedle 71 again begins its downward movement, and the loop-holder beginsto recede, the thread at the side of the latter is looped suilicientlyto allow the needle n to pass through it into the fabric, while theloop-holder, continuing its receding motion, draws thethread over theedge of the fabric and beneath the same. At the next movement theloop-holder carries the under thread through the loop of needle-threadat the side of the needle a, over the edge of thefabric to its firstposition, where the loop is again secured to the top of the fabric bythe needle-thread as before. It will be observed on reference to fig. 3that the needle,'in commencing its downward movement, passes theloop-holder on one side of the latter, and that as the needle approachesthe limit of this movement it passes the loop-holder on the oppositeside of'the same; in other words, the path traversed by the needlecrosses that traversed by the loop-holder, and, consequently, as bothneedle and loopholder begin to rise, there is more certainty of theloop-holder passing through the loop of needle-thread, and both needleand loop-holder descend) of the needle passing through the loop of underthread than if their paths were parallel with each other. I

It will now be seen that the loop-carrier will convey loops of threadfrom the under side and, upwards across the edge of the fabric to belocked to the same by thenoedlc-thread, and that the stitch produced isprecisely the same as the double-threaded stitch described in our patentof July 26, 1859,;reissucd February 9, 1864.

p In place of the rod D forimparting a vibrating .motion to the segmentthe latter may be operateddirectly from a rotary shaft, II, (fig. 5,)from the'cnd of which a pin, 7', projects and works in a slot, k, in thesegment. in the upper edge of the lattqr are slots z',-into whichproject pins (1 from a disk on the outer end of the rod a so tiiat,aszthe' segment vibrates, the desired inofrement will be imparted to theloop holder. Instead of tile segment F a sliding-plate, G, may be used,6,) the pins e on the end of the rod a projecting into slots-i on.

the upper. edge of the plate G. 1

We claim as 9111 invention, and desire t ovsecure by Letters I ?atent--.The arrangement and combination, lierein described, of ,the inclinedvibrating needle-arm E, its eye-pointed needle n, and the vibratingloop-holder or carrier 6, for the purpese specified. v
